* device tree support addition for the Exynos4 architecture.
*
* For drivers that require platform data to be provided from the machine
* file, a platform data pointer can also be supplied along with the
* devices names. Usually, the platform data elements that cannot be parsed
* from the device tree by the drivers (example: function pointers) are
* supplied. But it should be noted that this is a temporary mechanism and
* at some point, the drivers should be capable of parsing all the platform
* data from the device tree.
